If I grab just the video (not audio), it works fine, like in:

/usr/local/bin/ffmpeg -xerror -loglevel info -f x11grab -framerate 25 -video_size 1920x1200 -i :0.0+0,0 -dcodec copy -vcodec libx264 -y /home/fraga/src/qx11grab.mp4

Any hints?

A workaround is to use the -af aresample=async=1 parameter.
